POSSIBLE NICHE MIGRATION ON MARS BASED ON THE MIGRATION OF THE WATER

摘要

Theory of the migration: The ancient surface niches can sink deep during the global cooling and can apperar on the surface again only warm periods, in the modell the "living warmup" phase. The freshness of possible fossils depends mostly on the chemical environment. If we count on the stability of fossils, so we count only on time since the warm period in the fossils' point of view, the later are the fossils the more desin-tegrated condition they have. Based on this model the best places to look for relative intact fossils are the places of relative recent "living warm ups". Because it is difficult to drill deep under the surface, this model and its effect is important in the looking for signs of ancient life on the surface. If there were any life form on Mars it is more probable that there were primitive life forms than evolved creatures - and in this case the chemical desintegregation is very important factor again.
